Trained physicist Tschira helped establish German software company SAP with four former IBM colleagues. Now retired, although still on SAP's board, he concentrates on running his Klaus Tschira Foundation dedicated to pursuing whatever scientific research and cultural projects capture his imagination; for instance, sponsored a Brubeck Family Christmas Concert last December. His foundation is located in Heidelberg in the Villa Bosch, former home of German Nobel Prize-winning chemist Carl Bosch.
